That's the point. Have you played Eador 1? It had a much more subtle combat music, not like what you discribed. I like combat music, listening to the same tracks over and over becomes boring, it's better if something different brakes it up from time to time."durr, there is a combat so music should be energetic and loud and grandiose and fast, like a symphonic orchestra covering sex fucking pistols". Screw combat music.
Anyway, I also have problem with the music and the sound effects. Combat music sometimes doesn't start, sometimes it starts, but the original music keeps going during it. The hit-damage sound effects are not playing sometimes.
And although the new music is similar to the original one, it was "enhanced" in some ways. I liked the original more, it would be good if someone could mod it into Eador 2.
